3.2.18.7 Types of Chimney Tops and Vent Caps
Chimney tops vary in shape and size and configuration. The vent cap selected for installation will require some modification to fit
various chimney top types. Consult with your vent supplier.
Single ZC Flue Cap
Clay Liner Cover
Metal Cap on Clay Liner Chimney Top
Concrete Cap Chimney Top
For installation of this Insert’s vent cap with chimneys that have an existing metal, stone or concrete cap, Do
Not use “low profile” vent caps. They are vulnerable to exhaust recirculation and ghosting flames problems.
Always use full size vent caps and allow a minimum 3” clearance from vent cap top to the chimney cap. For
wider chimney caps and slabs, greater than 16” wide, increase the clearance above the vent cap to 6”
minimum. If necessary, raise the slab to supply the required clearance.
